    "question": "根据文档中的案例，当Deepseek检测到SQL注入风险时，它推荐使用哪种方式来修复？",
    "options": [
      "对用户输入进行严格的字符串过滤",
      "改用 PreparedStatement 进行预编译",
      "使用ORM框架如MyBatis自动处理",
      "将数据库错误信息隐藏，不返回给前端"
    ],
    "correctAnswerIndex": 1,
    "explanation": "文档的“智能修复建议”部分明确指出，针对SQL注入风险，推荐的修复方式是“改用PreparedStatement”。这种方法通过将SQL命令和参数分离，可以从根本上防止恶意输入被当作可执行代码，是防御SQL注入的标准实践。",
    "source": "文档中「三、真实案例：用户管理系统漏洞检测」的「智能修复建议」部分",
    "hint": "思考一下，在Java JDBC中，哪种语句执行方式是专门设计用来安全地处理动态参数的？"
  },
  {
    "question": "在`exportUsers`方法的原始代码中，存在资源未正确关闭的漏洞。Deepseek对此推荐的智能修复方案是什么？",
    "options": [
      "使用 try-with-resources 语法自动管理资源",
      "在 finally 块中手动调用 close() 方法",
      "依赖JVM的垃圾回收机制自动关闭",
      "增加一个全局的连接池来管理所有流资源"
    ],
    "correctAnswerIndex": 0,
    "explanation": "文档中针对“流资源”问题的修复建议是“推荐try-with-resources语法”。这是Java 7及以后版本中处理实现了`AutoCloseable`接口资源（如文件流、数据库连接等）的首选方式，它能确保资源在使用完毕后被自动关闭，代码更简洁且不易出错。",
    "source": "文档中「三、真实案例：用户管理系统漏洞检测」的「智能修复建议」部分",
    "hint": "Java 7 引入了一个新语法，可以确保资源在代码块结束时被自动关闭，避免了冗长的 finally 代码块。"
  },
  {
    "question": "Deepseek的实现原理中，哪个步骤负责分析代码的“人际关系”，例如检查数据库连接是否成对打开和关闭？",
    "options": [
      "模式识别",
      "上下文理解",
      "智能推理",
      "增量扫描"
    ],
    "correctAnswerIndex": 1,
    "explanation": "文档中明确描述，“上下文理解”是分析代码的“人际关系”，并举例说明了检查数据库连接有没有“成对出现”（打开/关闭）。这表明该步骤超越了简单的模式匹配，能够理解代码间的逻辑和状态关联。",
    "source": "文档中「四、实现原理揭秘」部分",
    "hint": "这一原理不仅仅是看单个代码片段，而是理解代码之间的依赖和状态关系，就像理解人与人之间的关系一样。"
  },
  {
    "question": "根据「效果对比数据」表格，与纯人工审查相比，引入Deepseek辅助审查后带来的一个显著变化是什么？",
    "options": [
      "平均审查耗时增加，但误报率大幅下降",
      "漏洞发现率和误报率都显著下降",
      "漏洞发现率显著提高，但误报率也有所上升",
      "审查耗时和漏洞发现率都没有明显变化"
    ],
    "correctAnswerIndex": 2,
    "explanation": "表格数据显示，“Deepseek+人工”模式的漏洞发现率从78%提升到95%，这是一个显著的提高。与此同时，误报率也从5%上升到了12%。这表明工具在提高检出率的同时，也带来了一些需要人工甄别的“噪音”，符合AI辅助工具的普遍特性。",
    "source": "文档中「七、效果对比数据」部分",
    "hint": "请仔细查看表格中“漏洞发现率”和“误报率”这两行的数据，对比“人工审查”和“Deepseek+人工”两列的变化。"
  },
  {
    "question": "在与CI/CD集成的GitHub Action示例中，`fail_on: error` 这个配置项最可能的作用是什么？",
    "options": [
      "当Deepseek扫描发现 'error' 级别的代码问题时，会导致CI/CD流程构建失败",
      "仅在日志中记录 'error' 级别的问题，不影响流程",
      "当扫描工具本身运行出错时，CI/CD流程失败",
      "忽略所有 'error' 级别的问题，强制继续执行流程"
    ],
    "correctAnswerIndex": 0,
    "explanation": "在CI/CD（持续集成/持续部署）流程中，`fail_on` 或类似参数通常用于设置质量门禁。`fail_on: error` 意味着一旦代码审查工具检测到严重程度为 'error' 的问题，就应该中止当前流程（例如，阻止代码合并），从而保证进入代码库的代码质量达到最低标准。",
    "source": "文档中「五、进阶使用技巧」部分",
    "hint": "在自动化流程中，我们通常希望在发现严重问题时能够自动“阻断”发布流程，以防问题代码进入生产环境。"
  },
  {
    "question": "根据文档「开发者常见疑问」部分，开发者应该如何看待Deepseek的审查结果？",
    "options": [
      "将其视为有价值的“建议”，但最终的决策权仍在开发者手中",
      "必须无条件采纳和修复所有报告的问题",
      "可以完全忽略，因为它经常误判",
      "仅用于指导初级开发者，资深开发者无需关注"
    ],
    "correctAnswerIndex": 0,
    "explanation": "文档中的问答部分将Deepseek的输出比作“导航偶尔会绕路”，并明确指出它给出的是“建议”而非“判决”，最终决策权在开发者手中。这体现了AI工具作为高效辅助而非强制命令的角色定位。",
    "source": "文档中「六、开发者常见疑问」部分",
    "hint": "文档中用了一个比喻来形容AI工具的输出，强调了开发者作为最终决策者的角色。"
  },
  {
    "question": "在`getUserRole`方法的案例中，为了解决潜在的空指针异常（NPE），修正后的代码采用了哪种现代Java特性？",
    "options": [
      "使用三元运算符进行null检查",
      "使用 try-catch 块捕获 NullPointerException",
      "使用 Optional 类来包装可能为 null 的查询结果",
      "为 userId 参数添加 @NonNull 注解"
    ],
    "correctAnswerIndex": 2,
    "explanation": "文档中的“智能修复建议”和“修正后的代码”都明确展示了使用 `Optional.ofNullable`、`.map` 和 `.orElse` 来处理可能为空的对象。这是Java 8引入的一种函数式编程风格的特性，旨在提供一种更优雅、更安全的方式来处理可能不存在的值，从而避免空指针异常。",
    "source": "文档中「三、真实案例：用户管理系统漏洞检测」的「智能修复建议」与「修正后的代码」部分",
    "hint": "Java 8 引入了一个容器类，其设计目的就是为了更好地代表一个值存在或不存在，以帮助开发者避免空指针异常。"
